MOTIVE POWER.

SPECIFICATION forming part of Letters Patent No. 236,201, dated January v4, 1881.

i Application led October 13, 1880. (No model.)

To all whom it may concern:

Be it known that I, THOMAS R. WRIGHT, of Philadelphia, county 'of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Motive Powers, of which the following is a specification.

The object of my invention is a new and useful improvement in motive powers, too well described hereinafter to need preliminary description, and shown in the accompanying drawings, in whichf Figure l is a sectional view of myimprove motive power. Fig. 2`is a sectional pla-n of the same. Fig. 3 is a side elevation. Fig. 4 is a sectional plan, and Fig. 5 a transverse sectional view of a modification.

Ais a hollow cylinder, having an upper and lower spindle, a and a. On the outside of the cylinder radiate spiral wings or arms B, of which there may be any desired number. The spindlea has a bearing in and extends through the casing C, surrounding the cylinder A, and has attached to it any suitable mechanism for imparting power. The lower spindle, a', has its bearing in a projecting step, c, in the inside of the casing C, and is formed in the following manner: In the tubular projecting portion d of the cylinder A is screwed a bolt or screw, c, conical on the lower end, and in the upper interior end of the tubular projecting portion is fitted snugly the valvef. The cylinder A is filled with any suitable light gas, to lcounterbalance the entire weight of the same and remove all friction, the gas beingintrod need through the lower tubular projecting portion, d, and when sufficient gas has been introduced within the cylinder to counterbalance the weight of the same the valvefis allowed to rest on its seat, and is retained in said position by the pressure of the gas contained within the cylinder. The screw-plug e, With conical end, is then screwed into position.

In Figs. l and 2 the cylinderA is represented as contained within` a casing, C, the inlet gbeing led from any suitable position from which a current of air can be obtained; or'the inlet g can be a continuation of a chimney or other exhaust, so that the cylinder A will utilize the current of air ascending the same, but will not interfere with the draft. The air, entering the inlet g and striking the spiral arms B, will cause the revolution of the balanced cylinderA, and then pass out through the outlet h.

In Fig. 3 the cylinder A is represented as exposed. It will be evident that a current of airin any direction, strikingthe radial spiral arms or wings B on the cylinder, will cause the rapid revolution of the same.

In Figs. 4 and 5 is represented a modification of the above. Contained within acasing, C, are three cylinders, A, which can be connected in any suitable manner. A current of air entering the inlet g and striking the arms B of the cylinders A causes the revolutionl of all of the cylinders A, and thence passes out of the outlet 7c.

It will be evident that by thus balancing the cylinderA no resistance is offered to the revolution of the same, and I am enabled to get the full power of a current of air directed against the cylinder.

I do not desire to restrict myself` to the use of a single cylinder, A, as two or more of the cylinders connected together may be used advantageously, as described above, either wit-hin a casing or arranged to be operated on while exposed to the air from all directions.

What I claim as my invention is- Ihe cylinder A, with the radiating arms B, lled with any light gas to counterbalance the entire weight of the same, and provided with an'inlet, d, controlled by a valve, f, substantially in the manner described.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesse.
